Question

Anyone could help me doing this?

For example I have a string of

SOME of the STRINGS are in CAPITAL Letters

What I want exactly for the output is

Some of the Strings are in Capital Letters

Only those in UPPERCASE will be turn their first letter to capital and leave the rest as lower case.

How can I achieve this using PHP?

Thanks in advance.

Thanks for the answers, really helpful and it gives me ideas.
I use preg_replace as well, just sharing to those who might need it too.

preg_replace('/([A-Z])([A-Z ]+)/se', '"\\1" . strtolower("\\2")', $str);

OR

preg_replace('/([?!]{2})([?!]+)/', '\1', $str);
